Depending on the season, our availability varies. The sooner we receive all the documents and information we need, the sooner we are able to begin the project.
It depends on the size of the house. A standard-sized shingled roof usually takes one or two days, weather permitting. For flat roofs, it can take about a week.
Depending on the size of the house, a crew will usually consist of between three and five workers. Here are some of our crew members.
No. You don’t have to be home, but it is preferable if you are so we can show you different product samples, talk about your roof, and have you meet our estimator face to face.
Yes. For the duration of the project, we will be need to place a bin or trailer either on the driveway, or on the grass, where we can dispose of the old shingles and garbage. Our crews also need the driveway in order to park and get equipment onto the job site.
No, you don’t need to put up any money before the project starts. If a roofing company asks you for money upfront, that should set off a red flag. In Alberta, a contractor has to have a special licence registered with the government to ask for money up front.
That being said, some roofs are very large, so sometimes a contractor may ask for a progress payment. That’s when the homeowner is satisfied with progress at about 40% or 60% completion. At that point the homeowner may pay some funds. If a contractor asks for money up front before even starting and without a licence to do so, move on.
When we work on your roof, we are there from start until finish. It serves no purpose for us or the customer to pack up, leave, and come back again. The last thing to do and the only application that is sometimes delayed by a few days is the perimeter metal flashing. The metal is measured and custom made by a different department.
Whenever propane, hoses, and fire are present there are very strict protocols, rules, and guidelines to follow to minimize all risks. Updated fire extinguishers, thermal heat sensor devices, and mandatory two-hour fire watches after the last torch is shut off.
Also, take note that a roofing contractor is not permitted to torch directly on any flammable substrate. We have other materials present so this does not happen. As I mentioned before, make sure your roofing contractor has open flame insurance and an active insurance policy account. This is very important!
Yes. Both of these are essential and you shouldn’t hire anyone to work on your roof without them. If anything were to happen, you (the customer) could be liable. So be careful!
Edmonton really promotes the use of the Better Business Bureau (BBB). Look for references and testimonials, and don’t rush into anything.
A reputable roofing company will also work with a roofing inspector. Bounce around the idea that you may hire an inspector to watch over the job, and then feel out the response of the contractor. Additionally, ask for proof of open flame insurance, WCB, etc. You can even phone their insurance company and have them fax or email a policy number. Doing this protects you!

This is a very good question. Every roofing contractor starts out somewhere, so this does not mean that just because he is new that he will be inexperienced. I know that NAIT (Edmonton) and SAIT (Calgary) run the flat roofing apprenticeship program. It’s a four-year course.
Most good roofing contractors have at least met this minimum requirement before they start out on their own, and preferably have also run a crew for a few years for a bigger company. It wouldn’t hurt to ask your prospective roofing contractor to show proof of his journeyman papers. Typically, electricians, plumbers, and HVAC tradesmen hold these credentials on their person. Roofers should be proud to do the same. The owner of Crest Roofing & Co has been in business since 1998 and roofing for over 30 years.
A reputable roofing contractor pays good market value for his journeymen and apprentice roofers. His men should not be rushing to do things quickly and incorrectly. Material is expensive, and a contractor should not be cutting corners.
In order to hire a contractor as a homeowner, you should get three quotes, look at them all, and then choose carefully. Don’t be fooled by the extremely low priced bids. Yes, it usually does mean it’s too good to be true.
Materials Used on your Roof
Yes, a synthetic underlayment is placed over the entire roof in order to create a vapour barrier that protects against water leaks.
Included in our quote is the installation of a 44” ice and water guard along all eaves and valleys. This membrane protects against any damage caused by ice damming, which is the freezing and thawing of the snow that happens here in Alberta.
Drip edge is a piece of galvanized metal that is installed at the edge of your roof along the eaves. It has a little lip that helps guide water into your eaves troughs instead of flowing over or behind and down the fascia. Drip edge also protects against the buildup of ice along the eaves.
It really depends on the age of your house or building. We’ve seen older flat roofs both with and without a continuous ridge vent.
The key is to understand that R-value wasn’t a huge priority back in the day because gas was cheap. However, these days, homeowners are doing more and more upgrades to their homes, and more focus should be on vapour barrier and air flow. If a roofing contractor doesn’t have an answer for you, they should consult with a proper roofing engineer/inspector. Not every flat roof requires a ridge vent, but some definitely do. Every roof is different.
Yes, there are many products out there. Each product in my opinion has its pros and cons for certain roof applications.
EPDM Single Ply Rubber Membranes are more suited for the bigger warehouses.
PVC Single Ply Membranes are mostly a specialty membrane commonly put on sun decks.
Hot Air Welding is good, but you’ll probably pay more in labour to install it.
Tar and Gravel is and always has been a very good method. If a customer wants us to go with what has worked on his home for 35 years then we comply; he may have a very good reason.
SBS Modified Roof Membrane System is the most commonly used product these days, and most schools, hospitals, and churches are putting this product on their roofs.
Shingle and Shingled Roof Questions
Shingle lifespans vary, but each has at least a 10-year “Right Start” period, where the manufacturers offer full coverage of materials and labour if there are any manufacturer defects. After this 10-year coverage period, the shingles become “prorated,” meaning that a certain percentage of coverage decreases each year.
Each product has different color options, depending on the shingle you decide to install. The estimator will be able to show you different color samples for the product. The color options can also be found online.
We will offer you a similar shade, but very rarely are the same products that were used initially still available.
These days everyone seems to be into recycling. We tear off and dispose of the existing tar and gravel membranes. If the existing insulation is dry and in good shape, we recommend leaving it and giving you the option to add on top of it. We usually have already done a cut test or walked over your roof to determine this. If some insulation is wet, then we simply isolate and remove the wet insulation and replace it with an equivalent R-value product.
One of the most frequently asked questions before we give a quote is, “What R-value do I have on my roof?
First of all, an R-value is the measure of resistance to the flow of heat. The higher the R-value, the better insulation.
The only way to find out your roofs R-value is to do an extensive cut test to assess the following:
- What kind of vapour barrier you have
- How much pink insulation you have in the rafters
- If you have a vented roof system or a commercial type BUR (built-up roof) system
If you have a vented system, then a little more work and labour is involved if you are adding R-value. It means pulling boards or planks, plugging off cold air venting, and adding R-28 insulation in your rafters.
We will even caulk around your existing light boxes (we add an acoustic sealant and caulk to the existing vapour barrier) because when your house was built, the builders may not have done that.
Whatever R-value the customer wants, we try to attain at a very reasonable cost. One of the biggest concerns we have heard from inspectors and architects over the years is the assurance that customers do not end up with two operational vapour barriers. This would trap air which becomes stagnant, giving rise to mold.
Each and every roof is unique, and there is always a solution!
If we can’t find the solution, then we call in a roofing consultant to make sure we can provide you with total satisfaction and complete peace of mind.
Yes, this is the best time to add R-value to your home. We know it’s expensive, but once you have the old membranes off, it’s the best opportunity to add more insulation.
We suggest a minimum 1″ to 1 1/2″ poly ISO insulation. It’s rated as R-6 per inch, and added to your existing insulation, you should notice a huge difference. You can go all the way to 3 inches or more if you want. That way you’ll really are maximize your energy savings.
Tar and Gravel Roof and SBS System Roof Questions
SBS is a type of modified bituminous membrane for flat roofs. It’s a hybrid roofing that combines built-up ply sheets. It is commonly known as Torch-On roofing and is the most common and proven membrane for harsh Canadian winters.
This would be under the category of preventative maintenance. Yes, these blisters can be fixed.
The original roofing contractor may have trapped moisture by being caught in a sudden rainfall during installation. We simply scrape away the gravel around the blisters by 12 to 14 inches, cut the blister out, and add two new plies to the existing membranes. These should be fixed because anyone doing any kind of maintenance on the roof, like shoveling snow, could step on one of these blisters and create future problems.
Yes, one can usually fix or repair a tar and gravel roof if it’s less than 30 years old. We can still do our best to repair a roof older than that, so long as the homeowner or the previous roofing contractor has not poured any cold process liquid over top of the gravel and asphalt. The reason I say this is that a cold process application cannot be scraped to receive a new membrane for a repair.
No, absolutely not. If a roofing contractor suggests this please move on to the next contractor.
For one, we don’t know what kind of shape the existing insulation is in. For example, the wood deck could have rotten boards. Second, gravel is installed at 60lbs per sq ft. Leaving this unnecessary weight and then adding a new roof on top of it makes it far too heavy. Not to mention our harsh Canadian winters. Ethically speaking, the old membranes have to come off, then you can fix or add insulation, and then you can install a new lightweight membrane.
First of all, we keep a very close eye on the weather. We are constantly checking the weather app on our phone to ensure we are not taken by surprise. In case of a sudden downpour, we have large tarps to protect your home in a pinch. Also, we always install a temporary two-ply seal to protect your home overnight.
We receive this question a lot. We get the frustration, as well as fully understand the expense of replacing a flat roof membrane.
There are some horror stories out there of some bad roofing contractors, where the roofs only last 10 or 15 years, or the repairs haven’t held or fixed anything.
The bottom line is that customers have to do their history check on the prospective roofing companies. Yes, you could hire a carpenter, purchase trusses, and install shingles, but we feel a customer will be way over budget going the trusses and shingle route. Instead, hire a professional roofing contractor who will install a good SBS (Styrene-Butadiene-Styrene) membrane should last well over 25 years with little maintenance.
There are a couple of things we can do. One is to add more drains or scuppers, but this is not always effective.
What we highly recommend is adding a slope package. This is done by taking measurements of the roof, marking where the drains are or about to be added. Then we look at your parapet walls to see how thick the polystyrene insulation can be applied.
Some customers go with 1% slope and some go as far as 2% slope. We then send the drawing to the people who will design and custom make your insulation. We also have to remember how thick we go on the outside walls because we then have to build up the parapet walls with wood blocking or a pony wall to compensate for the extra thickness of insulation.
Anytime a roof has a drain that goes through a warm house/building then out to the city a drainage system is always the best. These particular drains never freeze up.
However, there are some cities and towns where they want the house and building owners to add scuppers instead of drains. Less stress on the drainage system could be one of the reasons. These outside drainage scuppers work, but not that well in the winter because they stay frozen most of the time.
Simply call your town office and seek the proper contact to get the best information. Additionally, a good roofing contractor will take note of the landscape to get the best drainage possible.
